Definitions

  • the present invention relates to a tripod assembly and, more particularly, to a tripod assembly having a positively defined upright position.
  • a tripod assembly in which a bearing ring dimensioned for receiving a load bearing standard is hingedly coupled at the bottom portion thereof to three legs, each terminating in a flattened foot pad portion or pod on one end and having a squared flat surface bearing portion at another end dimensioned for cooperation with flat surface recesses in the outside walls of the bearing ring for effecting a positive limit or positioning in its upright operable position.
  • the legs When the assembly is lifted off its bearing surface, three legs rotate downwardly to a vertical position under the bearing ring.
  • the legs are hingedly coupled to the bearing rings at downwardly extending mounting eyes, each having an outer surface flush with a different recess, which allows for an extremely compact folded position for shipping, storage, etc.
  • An object of the present invention is the provision of an improved tripod assembly.
  • Another object of the invention is the provision of a tripod assembly having a positive upright positioning.
  • a further object of the invention is the provision of a tripod assembly which folds to an extremely compact position.
  • Yet another object of the invention is the provision of a tripod assembly which is inexpensive to manufacture and assemble and extremely convenient in use.
  • FIG. 1 is a perspective view of the preferred embodiment of the present invention in its upright position
  • FIG. 2 is a perspective view of the embodiment of FIG. 1 in a folded position
  • FIG. 3 is a cross-sectional view taken along lines 3--3 of FIG. 1.
  • a bearing ring 11 has an outside wall 12 and an inside wall 13. Hinge extensions 17 are hingedly attached to legs 16 at axle members 14.
  • Axle members 14 can be of any conventional construction.
  • Legs 16 have a T-shaped cross-section with a flat top portion 15 and terminate in flattened foot pads 18.
  • Foot pads 18 have extended bottom surface 19.
  • Flat surfaced recesses 21 cooperate with flat terminating surface 20 on top member 15 in forming a bearing contact.
  • a standard 22 is (shown in phantom) being received by bearing ring 12. Inner wall 13 of bearing ring 11 is tapered to more firmly contact and support standard 22.
